TIP-INS

Gonzaga: Wiltjer missed the final 5 minutes of the Zags' quarterfinal win over San Francisco on Saturday after landing on his left hip, but he started Monday's game. He scored just three points in the first half but made three consecutive 3-point shots during Gonzaga's pivotal run.

Pepperdine: The Waves were hoping to reach the WCC conference tournament championship game for the first time since 2002. Instead, they suffered their 29th consecutive defeat to Gonzaga.
